<H2>polygon</H2>
<HR>
Generate polygons from the command line.

<H3>Shortcuts:</H3>
   <BLOCKQUOTE>
      None.

<H3>Usage:</H3>
   <BLOCKQUOTE>
      <B>polygon</B> <I>type x1 y1 x2 y2</I> ... <I>xn yn</I> <BR><BR>
      <BLOCKQUOTE>
         where <I>type</I> is a tile type to draw, and <I>x1 y1</I> ...
	 <I>xn yn</I> are <I>n</I> vertices of a polygon.
      </BLOCKQUOTE>
   </BLOCKQUOTE>

<H3>Summary:</H3>
   <BLOCKQUOTE>
      The <B>polygon</B> command allows generation of polygons on the
      layout from the command line, similarly to the <B>wire segment</B>
      command.  The <B>polygon</B> command automatically generates the
      proper tile geometry for the polygon as specified by vertices.
      Vertex points are pairs of X Y coordinates, and may take any
      dimensional value (default lambda, but may be internal units or
      metric units).  Note that polygons should be convex;  the tile
      generation algorithm is not guaranteed to work with non-convex
      geometries. <P>

      While simple non-Manhattan structures (triangles) can be generated
      with the "splitpaint" and "spliterase" commands using macros, there
      is no convenient interactive method for generating complex polygon
      geometry.  The <B>polygon</B> command is best used in scripts to
      create specific patterns based on known geometry.

<H3>Implementation Notes:</H3>
   <BLOCKQUOTE>
      <B>polygon</B> is implemented as a built-in command in <B>magic</B>.
